Description

A kind of novel single-phase magnetic voltage regulator

Technical field

The utility model relates to a kind of transformer, particularly a kind of single-phase magnetic voltage regulator.

Background technology

The core structure of existing single-phase magnetic voltage regulator is a four-column type; Coil has four groups, promptly transformer once, secondary coil, be placed on two inner props, reactor reactance, control coil are placed on two column jackets; Transformer once, secondary coil can only connect; Reactance coil can be connected into parallel connection or series connection, is good with parallel connection, and in order to offset the alternating current impression electromotive force, two DC control coils can only be connected and can not parallel connection; Magnetic flux distribution in four posts is inhomogeneous; Unloaded range of regulation is little, can not realize unloaded pressure regulation, simultaneously in order to reduce production costs, and makes device fabrication reasonable, does not allow the electric supply installation volume too big, and therefore existing magnetic voltage regulator must need further improvement.

The utility model content

For addressing the above problem, the utility model makes its structure compact more through a kind of novel single-phase magnetic voltage regulator is provided, and effectively material consumption reduces, thereby has reduced load loss, can realize unloaded pressure regulation, the wide effect of load range of regulation.

For reaching this purpose; The utility model provides the said magnetic voltage regulator of a kind of novel single-phase magnetic voltage regulator to comprise main iron core; Two auxiliary iron cores are provided with secondary coil on the said main iron core, on said two auxiliary iron cores the DC control coil are set; Said two auxiliary iron cores are arranged at the both sides of main iron core, and the outermost of said main iron core and two auxiliary iron cores is wound with primary winding.

As a kind of improvement of the utility model, said primary winding, secondary coil adopt connection in series-parallel to connect.

The described single-phase magnetic voltage regulator of the utility model makes its structure compact more through no reactance coil, like this, need not reactor winding, can effectively reduce the consumption of material, thereby reduce load loss, can realize that unloaded pressure regulation, load range of regulation are wide; And because the advantage of this structure makes primary winding, secondary coil can adopt serial or parallel connection to connect flexibly, so solved the limitation that four stem structure magnetic voltage regulators can't satisfy user's specific (special) requirements.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Each member is among the figure:

1, main iron core 2, auxiliary iron core 3, secondary coil 4, primary winding 5, DC control coil.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done detailed explanation:

Single-phase magnetic voltage regulator as shown in Figure 1; Comprise main iron core 1, auxiliary iron core 2, secondary coil 3, primary winding 4, DC control coil 5; Be wound with secondary coil 3 on the said main iron core 1; Be wound with DC control coil 5 on said two auxiliary iron cores 2, said two auxiliary iron cores 2 are arranged at the both sides of main iron core 1, and the outermost of said main iron core 1 and two auxiliary iron cores 2 is wound with primary winding 4.

During work, with the main iron core magnetization, export voltage through secondary coil 3 by main iron core 1 through primary winding 4 for input voltage; There are two auxiliary iron cores 2 on main iron core 1 next door, on auxiliary iron core 2, is wound with DC control coil 5, and DC control coil 5 is connected to the DC power supply that can regulate size of current; Through regulating the size of current of DC power supply; Thereby change the magnetic flux size of auxiliary iron core 2, the magnetic flux size through auxiliary iron core 2 and then change the magnetic flux size of main iron core 1, thus reach the size that changes output voltage; Owing to can change the size of current of direct current power supply arbitrarily; And then can control the degree of saturation of auxiliary iron core, thus change the size of secondary voltage, realized that load voltage is adjustable continuously.

The above; It only is the preferred embodiment of the utility model; Be not to be the utility model to be done the restriction of any other form, and, still belong to the utility model scope required for protection according to any modification or equivalent variations that the technical spirit of the utility model is done.
